I was just about to purchase this kit, when I read about the questionable xover design. During this research, I read where several members have re-worked the xovers for proper sound. Can anyone steer me towards any threads where this information is shared?
Thanks

Must be flowing in money when 2 grand is not a problem for a diy product. My advice is this. You appear to be an American citizen, so buy American.
Okay, that's a strange response. Flowing in money? How about I worked my *** OFF to earn this $2000 to spend on DIY speakers. So no ... I am not flowing in money.
As far as the xover needing a reworking ... There is quite a lot of press which people who have heard them, are saying the xover is just not "right" yet. Seems the sound is a bit off for $2000 worth of parts. This seems to be an almost general cencus on this particular xover. Leading several people to rework and improve the xover.

At least one german audio magazin uses the Nada as their reference loudspeaker.
So the question is, does the other reworked crossovers have a better sound or do they sound different?

Flaxxer,
Have you seen the new Purifi Audio drivers?
PTT6.5W04 - PURIFI
They have a bookshelf design too:

Should match your goal of building a premium quality bookshelf speaker?

My main goal was a two way, using either Arum Cantus or Mundorf AMTs. Not finding such an available kit, other than the Bordeaux, my second choice would be Illuminator drivers. Something beryllium tweeter. This is all my goals are.
Flaxxer,
is there a way to be sure that spoken words on Nada crossover are trustworthy?
If your faith in this kit is shaken, then there is not much you can do about it, I suppose.
It is not my intention to analyze this kit and I do not think much of published graphs either but in general the crossover filter is one of possible solutions. Whether it will match people's taste, I do not know. I know for a fact that 2 grand has absolutely nothing to do with the way it sounds as a package. You can change its sound significantly for 20 bucks worth of passive parts, for the better or worse.
To further clarify on my suggestion that sounded strange to you, a Bagby design "Spirit Wind" would be a safer bet, and a lifetime keeper if you can forgive relatively older drive units technology, unlike illuminator units.
Good luck with your quest.

Flaxxer,
The Purifi reference design uses a Mundorf AMT (AMT21CM2.1).
However, have not seen this in kit form.

So just so everyone knows, I am NOT down on the kang ton speakers. BUT this thread has me fairly concerned : http://https://www.diyaudio.com/forums/multi-way/299303-klang-ton-nada-2-a.html
It speaks of really high xover points and other xover issues. It also discusses how several members have reworked the xovers.
There was at least one published re-work of the Nada crossover, but damn if I can find it. 🙂

I have the 18U/8741T00 in a 13” 3-way. It’s crossed just below 2kHz. Anything above 2kHz results in beaming and break up modes which will cause extreme stridency and ringing. It really needs a tweeter that can handle down to 1.7kHz, like the 71000. The trade off is distortion on the tweeter if it’s crossed too low. But, the Scan-speak drivers are top-notch! I love the wide dispersion on the 71000. You might want to look into Troel’s Monitor that use the 18U and 71000. The all-pass filter sounds good, however (6) 10uF high-end film caps will be a fortune!
I don't know if you are aware but the built follow-up design of the "Nada" called "Todo". I guess if you are going to use your hard earned cash you might want to go for the latest version.
DM me and I can send you the details. Might be more expensive and is a rather big floorstander
